PATENT om-cs r ERIC 0. MOORE, OF ROCHESTER, NEW: YORK, ASSIGNOR T0 JOHN CQMOORE conPoRA- TION, 0F nooimsrnnfnn w yonx, A ooRPoRATIoN on NEW YORK" LOOSE LEAF BINDER Application filed September 25, 193d Serial No. 484,300. 1

My present invention relates to loose leaf binders and particularly to those of the type in which the perforated leaves of the book are impaled upon posts mounted on onebook 5 cover and having their ends locked with the other book cover when the binder'is closed, and the invention has for its object to provide a simple, strong, and efficient all-metal construction for the back of the book or binder, 1 which construction can be produced at low cost from sheet-metal parts that are easily assembled. A further object ofthe invention is to provide in connection therewith a simple, but strong and durable, means, easily operated, for locking the ends of the impal ng posts carried by one cover to the other cover.

To these and other ends, the invention residesin certain improvements and combinations of parts, all as will beih'erein'after more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Fig. 1 is an edge View of a loose leaf book or binder taken endwise of the hinged connections thereof;

Fig. 2 is a plan view of the binder in open position with the transfer posts and leaves removed;

Fig. 3 is an end view of the same.

Fig. 4 is a section through the binder in the region of its locking devices taken on the line 44 of Fig. 1; V

Fig. 5 is a collective rear or outer side view of the several hinge portions of the cover, those portions of one side being in disconnected and separated relation;

Fig. 6 is a plan view of the locking bolt;

Fig. 7 is a section on the line 77 of Fig. 2;

Fig. 8 is a section on the line 8 8 of Fig. 2; and j Fig. 9 is a section on the line 99 of Fig. 2.

Similar reference numerals throughout the several views indicate the same parts.

Referringfirst to Figs. 1, 2, 3, and 4, the major elements of the binder, when it is completely assembled, comprise covers 1 hinged on pintles 2 to intermediate portions 3fand 4 which in turn are hinged on pintles 5 'to a 59 back plate6 so that the binder may be laid out in the flat condition of Figs. to

receive the perforated leaves or sheets. To

first describe generally theconstruction and mode of operation, the connectin portion 3 has anchored therein a pair of impalin posts 7 upon which the leaves or sheets are impaled, as shown in Fig. 4 (dotted lines, F ig."1). The upper or free ends of these posts are received in apertures or socketsf8 in the connectingportion 4when the binder covers are closed down upon the sheets to selected number of the sheets A may be re-- moved from orfa'pplied to the posts Z'c'ollectively without disarrangement in a wellknown manner, but this transfer element forms no partof my present invention. I

' The connecting elementsS and 4 are tubue lar, are preferably rectangular 'in 'cros ssection, and are made up of sheet-metalparts in, a manner hereinafter described The element?) is filled by a metallic core 13 in which the posts 7 are riveted, as shown in'Fig. 4.

The other connecting element 4 is hollow and contains the slidinglatch plate 14, shown in Figs. 4 and 6. 'The body .ofthis' plate'lies' flat against what maybe termed thetop of tubular connecting element" 4, in f Fig. 4, or

the bottom inner surface thereof, in Figs.

2 and? His provided, however, with offset portions 15 having apertures 16 therein that slide-into and outflof 'alinei'nent with the socket holes 8 for the posts 7, hereinbefore referred to. f The ends of theimpaling posts "7 have cut-away portions forming locking 16 of the latch member, 14 and areengaged and heldby the latterflunder lthe influenc e .shoulders 17-and as theyenterthe sockets 8, these shoulders project within the openings on the end of the latch plate and the closed end wall of the connecting member 4. At the opposite end an angular extension 2l'of the latch plate provides an operating member, pressure on which by the operator compresses the spring 18 and releases the ends of the impaling posts 7 so the bindermay be opened and flattened out for the application or removal of the sheets A, as in Figs. 2 and 3.

It will be seen from the particular construction of the latch bar l l with its body portionsliding against one wall of the tubular connecting element 4 and its offset post- 7 en a in ortions 15 ridin a ainst the 0 D D C b t posite wall that there is no opportunity for I posts is made solid by the filler 13', while the other one is tubular to accommodate the sliding latch. Each comprises an upper or inner channel member 22 with the lower edges of its side walls formed with laterally extending knuckles and alower cover plate 24 also provided with laterally extendmg knuckles 25,. Then 24 is placed on 22' to close it, the knuckles 25 (Figs. 5 and interspersed with knuckles 23. There being fewer of'the knuckles 25, this leaves other spaces between certain of the knuckles 23 for the similar reception of knuckles 26 on a cover connecting plate 27 at one side and the similar knuckles 28 on one edge of the back piece 6. Thisi'smade plain by a comparison 7 to 8) are wall and adapted to interlock with the looking shoulders of the posts.

2. In a loose leaf hinder, the combination with cover members, a back plate, and connecting members hinged at opposite sides to both, one of the connecting members being hollow and provided with apertures on its inner side and the other connecting member being provided with impaling posts, said posts being provided with looking shoulders, of a sliding latch member in the hollow connectingmember comprising a sheet-metal bar movable in contact with one inner wall thereof and having ofiset portions moving in contact with the opposite wall and perforated to interlockwith the locking-shoulders of the posts, and a compression spring interposed between one end of the latch bar and the adjacent endof the connecting member, the other 1 end f the latch bar being provided with a pro ecting operating portion, by means of which the' operator may compress thespring and release the latch from the posts.

3. In a loose leaf binder, thecombination with a cover plate, and a back plate, of a connecting member formed of a channelpiece having laterally projecting knuckles, and a cover plate therefor having laterally projecting knuckles interspersed with those of the channel piece, the cover late and the back plate each also having 'aterally proj'ecting knuckles interspersed with those of the channel piece to form-Va double hinge,

there being a pintle'in each set of knuckles serving as the pivots of the parts and also functioning to hold all of the aforesaid parts assembled. ERIC C. MOORE.

- of sections 7, 8, and 9, taken on Fig. 2'. The

endwise insertion of the pintles 2 and 5 finishes the asselllbly. It will thus be seen that a fully hinged all-metal back is produced with the use of stampings only, the parts of which can be rapidly assembled by unskilled labor.
